Embodiment 1
[0045] Such as figure 1 and figure 2 As shown, this embodiment proposes a cleaning system for distributed photovoltaic power plants, the system includes a water tank 1, a water pump 2, a solenoid valve 3, a main water pipe 4, a branch water pipe 5, a nozzle 6, a rain and snow sensor, a dosing Device 7 and processing circuitry.
[0046] Specifically, the water tank 1 can communicate with the main water pipe 4, and the main water pipe 4 is provided with a solenoid valve 3 that can be turned on and off by a processing circuit. A water pump 2 is provided between the water tank 1 and the main water pipe 4 for pumping the cleaning liquid stored in the water tank 1 to the main water pipe 4 for cleaning the photovoltaic modules. The start and stop of the water pump 2 is also controlled by the processing circuit. The main water pipe 4 is connected with a branch water pipe 5, and the branch water pipe 5 is provided with a nozzle 6, and the nozzle 6 can spray the liquid pumped by the...
Embodiment 2
[0054] Such as image 3 As shown, this embodiment proposes a cleaning method for the cleaning system of a distributed photovoltaic power station, wherein, the relevant content of the cleaning system can refer to the content recorded in Embodiment 1, and will not be repeated here. The cleaning method includes:
[0055] S101. Detecting rain and snow information in the surrounding environment of the photovoltaic module;
[0056] S102. When the rain and snow content in the rain and snow information exceeds a preset value, control the dosing device to add the deicing agent stored in the dosing device to the water tank;
[0057] S103. Turn on the water pump, and turn on the solenoid valves sequentially according to a predetermined turn-on sequence, so that the liquid added with the deicing agent in the water tank is sprayed to the surface of the photovoltaic module through the spray head.
[0058] Specifically, the detection of rain and snow information can be realized through the...
Embodiment 3
[0077] This embodiment proposes a distributed photovoltaic power station, the distributed photovoltaic power station includes the cleaning system described in the embodiment, which will not be repeated here.
[0078] In this embodiment, the liquid with cleaning properties in the water tank 1 is sprayed onto the photovoltaic module through the nozzle 6, so as to realize dirty cleaning of the photovoltaic module. At the same time, snow-melting agent can be added to the liquid to realize the function of spraying snow-melting agent in snowy days to melt the snow covered on the photovoltaic modules, thereby increasing the income of photovoltaic power plants, reducing operation and maintenance costs, and ensuring the safety of power plants.
